While focusing on performance, we touch on the science support needed for excellence, including nutrition. We also review how different exercise intensities demand different outputs from our energy stores and muscle fibers. For infographic, exam questions and mark schemes visit https://revisedirect.com

This episode covers Newton’s laws of motion (inertia, acceleration, reaction) and their application to sport.

We also look at forces like gravity, friction, and air resistance, and introduce concepts such as centre of mass, stability, and angular motion.

A guide to the heart's structure and the cardiac cycle, including the conduction system (SAN, AVN).

We explore factors affecting cardiac output, stroke volume, and heart rate, and how these values differ between trained athletes and untrained individuals.
